TO ALL WHOM IT MAY CONCERN:

Be itkncwn that I, JAMES M. SEYMOUR, of the city of Newark, in the county of Essex,.and State of New Jersey, have made certain Improvements in Machines for Cutting Miti-es on mouldings for picture-frames, or

for carpenters" use; and I hereby declare the following to be a full and exact description of the same, refer ance being had herein to thedrawings that accompany this specification-as part thereof.

The nature of my improvement'consists in the adaptation of a support for rebates and quirks, to obviate the breaking and defacing of mouldings, soeommonly occurring as mitring-machines are ordinarily made.

In the drawingsi Figure 1 is the mitre-machine with the supporton one side.

Figure 2 is a viewof the position of the moulding on the support.

Figure 3, the moulding without support; and

.Figure 4 is another manner of attaching an adjustable support. p

A, the bed-piece; B, the frame; C, the slide;` D, the knives, and E, the lever, are all constituents of the machine known-as'Halls' mitre.

F F show' two additional arms attached tothe frame F, projecting back'of and parallel to the knives D D A double clasp, G, slides upon the arms F F, through which passes the stem ofv the adjustable support H, which is secured Vto the arm F by the set-screw al The foret b, on the stem of H, is adjusted to the under side'ot the rebate in the moulding e, and is held in position by the set-screw d, on' the top of H, which receives and transmitst-he pressure from cutting the moulding onto the arml F. i l

i The'face oftheadjustablel support b must been a line with the cutting-knife D and with the angular bed A, the 'back ofthe `knife and its edge passing close. thereto, andY the arms F F must be on precisely the .same anglefso that ,in moving the foot 6,-by means of the stem' H -andthe double clasp G, up or down, out or in,`its face shall preserve thesame` angle with the knife and thel bed.

What I claim as my improvement, anddesire to secure by Letters Patent, is

1.` The-adjustable foot b, stem H, double clamp G, and the arms' F F, when combined with aimitrenachine in the manner and for-the purpose specified, K p

2. The adjustable foot b, when constructed to move on the lin of the edge of the knives, and close thereto, as specied'and shown.
